Officers were called to the Swift Street school around 4 a.m. when an alarm sounded. Officers discovered the intruder had broken a window in the food services building to enter it.

As of Friday morning, school personnel were still working to determine what, if anything, had been taken. Police are also working to obtain security camera footage from the school and finger prints were collected from the scene, deputy chief Steve Clark said.

The burglary was the fifth at an elementary school in Santa Cruz County in the past two months.

Police arrested a Watsonville man earlier this month on suspicion of burglarizing at least two elementary schools. Sheriff's deputies linked Jaime Vazquez Mendoza, 31, to burglaries at Mar Vista Elementary School in Aptos and Live Oak Elementary School in November. A library window was smashed at Mar Vista and the suspect apparently tried to steal several computers that were chained to each other, but nothing was taken.

In the burglary at Live Oak Elementary, someone entered a staff lounge through a window and stole a computer and printer.

There were also burglaries last month at Bradley Elementary School in Corralitos and Starlight Elementary School in Watsonville. A computer was stolen from Starlight but nothing was taken from Bradley. Deputy April Skalland said previously that investigators were probing whether Mendoza was involved in those incidents.

Mendoza was arrested Dec. 7 on suspicion of felony burglary and was booked into Santa Cruz County Jail in lieu of $25,000 bail. He is no longer in custody, jail records showed Friday.
